Description

Heavy-duty, multi-purpose high-pressure rotary blower

The ROOTS® RAM Series is engineered for high-pressure applications, utilizing externally cooled gas recirculation to help manage blower temperatures and support elevated discharge pressure levels.

• Delivers pressure up to 30 psig (2068 mbar)
• Flow capacity up to 670 cfm (1140 m³/hr)

Key Features

• Single-stage design capable of reaching 30 psig
• Removable steel mounting feet for flexible setup
• High-strength alloy steel timing gears
• Cylindrical roller bearings for durability under load
• Piston ring air seals to minimize leakage
• Hydrodynamic lip-type seal on the drive shaft
• Spur timing gears and drive-end bearings with splash lubrication

Benefits

• Innovative Discharge Cooling: The ROOTS® RAM DPJ WHISPAIR™ blower incorporates a proprietary discharge jet plenum that channels pressurized, cooled system air into the cylinder, enabling single-stage operation at high pressure.
• Reliable High-Pressure Performance: Built for continuous use at pressures up to 30 psig without relying on vanes, valves, or Teflon rings, reducing maintenance needs.
• Robust Build Quality: Constructed with ductile iron impellers on integral shafts, a rigid one-piece casing, and grey iron headplates for extended service life.
• Advanced Sealing: Piston rings and lip-style oil seals prevent internal air leakage and protect the air stream from oil contamination. A hydrodynamic seal keeps the drive-end leak-free.
• Lubrication You Can Count On: Spur timing gears, made from hardened alloy steel, receive splash lubrication at both ends for consistent, efficient performance.
• Installation Versatility: Mounting feet can be positioned for vertical or horizontal setups; extended shaft options are available to meet specific application needs.
• Extended Warranty Protection: Backed by a 24-month operational warranty or 30 months from the shipping date—whichever occurs first.
